土壤温度是土壤重要的内在属性,亦是反映区域环境特征和土壤系统分类体系中的重要基础性指标。但在贵州省境内,由于缺乏数据观测体系,目前还缺乏完整的土壤温度报道和估算方法。介于此,本文收集了贵州省境内84个气象站多年的地面气候资料数据,通过拟合土壤温度与年平均气温、纬度、经度和海拔高度之间的关系,构建了相应的土壤温度估算模型,并与其他三种地区性土温测算方法进行比对,得到了相对一致的分析结果。模型估算的区域土壤温度结果显示,贵州省各地区土壤温度以“热性土壤”为主(15℃≤Y<22℃),少数地区如:毕节的大方、威宁和六盘水的水城三个地方为“温性土壤”(8℃≤Y<15℃)。
Soil temperature is an important intrinsic property of soil and an important basic index reflecting regional environmental characteristics and soil system classification system. However, in Guizhou Province, due to the lack of data observation system, there is still a lack of complete soil temperature reporting and estimation methods. Hereby, this paper collects the data of ground-based climatic data of 84 weather stations in Guizhou Province for many years. By fitting the relationship between soil temperature and annual mean temperature, latitude, longitude and altitude, the corresponding soil temperature estimation model , And compared with the other three methods of regional soil temperature measurement, and obtained relatively consistent analysis results. Soil temperature in the region estimated by the model shows that the soil temperature in each region of Guizhou Province is dominated by “hot soil” (15 ° C ≤ Y <22 ° C). In a few regions such as generous Bijie, Weining and Liupanshui Watertown three places for “warm soil ” (8? ℃? Y <15? ℃).
